STOP-MOTION FOR MULES.

SPECIFICATION forming part of Letters Patent No. 553,195, dated January14, 1896.

Application filed October 30, 1895. Serial No. 567,363. (No model.)

' To all whom it may concern:

Be it known that I, FREDERICK LUsSIER, a citizen of the Dominion ofCanada, residing at River Point, in the county of Kent and State ofRhode Island, have invented certain new and useful Improvements inStop-Motions for Mules; and I hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification.

This invention has reference to improvements in devices for releasingthe well-known stopping mechanism.

The object of the invention is to automatically release the stoppingmechanism when portions of spindle-bands or waste of any characterbecomes wound around the driving-belt sufficiently to increase thediameter thereof.

The invention consists in the combination with the connecting-rod of thestop-motion and the hand-lever by which the same may be operated, of adetector-finger adjacent to the belt and connections intermediate thedetector-finger and the hand-lever to throw the same to a position wherethe connecting-rod may be operated by its spring when thedetector-finger is thrown by the contact therewith of a bunch on thedriving-belt.

The invention also consists in such other novel features of constructionand combination of parts as are hereinafter more fully described, andpointed out in the claims.

Figure 1 represents portions of the muleframe with the driving-belt, thehand-lever, and the connecting-rod shown in combination with thedetector and the connections between the same and the lever. Fig. 2represents an enlarged view of the detector and its connections removedfrom the machine, part of the driving rope or belt being shown inposition.

Similar numbers of reference designate corresponding parts throughoutthe views.

In carrying my invention into practice it has been my object to preventthe carrying of waste (from broken spindle-bands or from any othersource) by the driving-rope into positions whence it may be conveyedbetween gears or into contact with parts of the moving mechanism to thedetriment thereof. My purpose has also been to accomplish this objectning in its normal condition.

by the aid of simple and inexpensive mechanism which could be connectedwith the present stop-motion.

In the drawings, 5 represents the machine frame of the usualconstruction and furnished with the ordinary belt-pulleys 6, 7 and 8,carrying the driving belt or rope 9. Pivoted on the frame is the usualcrank hand-lever 10, the short arm 11 of which is pivotally connectedwith the well-known stop-motion rod 12, ordinarily operated by a springwhen the lever 10 is released. In my improved mechanism the short arm 11of the lever is provided with the pin 13. The rod 14 is journaledparallel to the axis of the pivot on which the lever 10 swings. On thisrod are mounted the finger 15, bearing on the pin 13 of the lever 10,and the clamping-block 16, having two perforations, each provided with aclampingscrew 17 and 18, working through a socket at right angles to theperforation. By the screw 17 this block 16 is secured to the rod 14:,while by means of the screw 18 the shank 19, carrying the detector 20,is adjustably secured in the block. The detector has the lateral arm 21curved atits end and the vertical arm 22 also curved at its end, toprovide for the free entrance between the arms of the driving belt orrope 9.

The shank 19 is adjusted in the block 16, so that the belt 9 just clearsthe arm 21 when run- Should waste or foreign material of any naturebecome engaged with the belt 9, it will ultimately be brought againstthe arm 21 of the detector, and meeting with resistance to its passagewill have a tendency to drag the detector along in the direction of thearrows a ain the drawings, causing the rotation of the rod 1 1 by thedetector and the throwing of the lever 10 by the pressure of the finger15 on the pin 13, thus allowing the heretofore well-known stop-m0- tionmechanism to act in the same manner as when the lever 10 is thrown byhand.

Having thus described my invention, I claim as new and desire to, secureby Letters Patent- 1. In a stop-motion of the nature described, thecombination with the usual hand-lever, and the stop-mechanism releasablethereby, of the driving-belt, a detector adjacent thereto adapted to beactuated by any material increase in the diameter thereof, and aswinging connection between the detector and the hand-lever.

2. The combination With the frame 5, the lever 10 pivotally mountedthereon and having the arm 11 provided With the pin 13, and theconnecting-rod 12 pivoted to the arm 11 and being the usual connectionbetween the hand-lever of a mule and its stopping-mechanism, of the rod11 mounted in bearings, the finger 15 adjustably clamped to the rod andbearing on the pin 13 of the lever, the perforated block 16 adj ustablyclamped to the rod 1-1 by the screw 17 and the shank 19 carrying thedetector 20 consisting of the arms 21 and 22 adj ustably clamped in thevertical perforation of the block 16, as described.

In witness whereof I have hereunto set my hand.
